GPU mining machine

1. Now we have to use a miner to dig the coins

The first step in setting up mining equipment is to choose the right hardware. This article will focus on GPU (graphics card) mining, of course, you can use CPU or ASIC equipment mining. Amd graphics card architecture is very beneficial to mining. NVIDIA card is not suitable for mining because of its low hash rate. The best NVIDIA graphics cards are less than 0.5 megahash. Notebook Hardware mining is not as good as NVIDIA card, which is a bad option for mining. You need to use a desktop system for mining. There is a desktop system to ensure adequate cooling of the hardware

the graphics card or card needs to be able to match the motherboard, and the power supply must have enough PCI-E connectors. Before determining the graphics card, pay attention to these. In order for the system to cool down sufficiently, you need to remove the cover of the chassis in order to get better heat dissipation. This is what people call "open air rig.". If you can aim the system at a fan or air conditioner, you can make the device cooler when it's running, thus extending its life and keeping it efficient

bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

4. Mining software, from the programming principle, is about large-scale parallel computing
there are many stream processors in GPU of graphics card. For example, the old HD5770 has 800 stream processors, which is equivalent to 800 computing cores. In recent years, the mainstream high-end graphics card has more built-in stream processors and more powerful computing performance. Using GPU for mining operation, the stream processor is used for parallel operation, and the mining program also optimizes the GPU parallel operation, so the operation efficiency is particularly high, and the efficiency of bitcoin mining has been greatly improved
the number of CPU cores is relatively small. At present, the number of the most powerful mainstream desktop processor cores is no more than 10 or 20 (many are logic cores virtualized by hyper threading technology), and the parallel computing power is far less than that of GPU.

5. Graphics card uses GPU's general computing power for mining calculation, and its performance is much better than simple CPU calculation, because GPU has a large amount of concurrency
the professional mining machine does not use GPU, but a special mining chip, which is an ASIC. This kind of chip can only be used for mining, and has no other functions, but it is highly efficient in its own work and faster than GPU.

6. GPU is the meaning of graph line processor, the original design intention is to do graphics computing. GPU chip is essentially a collection of many small CPUs for image processing. Of course, each CPU can also do general operations such as addition, subtraction, multiplication, division or non shift jump, so it can also be used for mining. When GPU is mining, it wastes less chip area and power consumption than CPU, so mining efficiency is higher than CPU
What about ASIC? It is a more optimized circuit than the CPU mentioned above. There is no specific definition, but there is a rule in the field of chip design: the more general computing platform, the less efficient it is to complete specific computing. ASIC is the most dedicated computing platform. If we understand this, we can come to such a basic conclusion: in the mining field, if we use the computing power proof mechanism, as long as the CPU can dig, ASIC can dig. No matter what algorithm is used, ASIC can dig. There is no reason that CPU can dig, but ASIC can't, So the biggest difference between GPU and ASIC is their specific computing power.

7. Graphics card miner is a mining device which supports a variety of mining algorithms. Different from ordinary graphics card, it is assembled by a number of high configuration graphics cards, customized and highly compatible chassis, professional mining rack and other equipment specially designed for mining needs. You can pay more attention to the interstellar bit miner.

8. A device that digs bitcoin or Leyte or other electronic money. Usually a computer motherboard has more than one high-performance graphics card.

9. This is what Tianhe-1 and Tianhe-1A do.
Tianhe-1 uses 6144 Intel general multi-core processors and 5120 amd graphics acceleration processors, with a total memory capacity of 98tb. The bandwidth of point-to-point communication is 40Gbps, and the total capacity of shared disk is 1PB. The supercomputer system will be deployed in the National Supercomputing Center in Tianjin Binhai New Area as the business host. Tianhe-1 adopts AMD's ati4870 and Tianhe-1A adopts NVIDIA chip

10. Only when GPU is too laggy will CPU help GPU and the machine will be stuck. If the graphics card is not enough, it is recommended to replace the video card.
